What is a performance warranty for Eaton lithium ion batteries?

The vendor warrants that when the battery is installed per vendor’s instructions, operated within vendors environmental guidelines, and charged by the UPS as specified, the battery system will provide at least 78-80% of its initial capacity at the 10-year mark. If the battery or string fails to provide that capacity, it will be replaced at no charge. Labor is not covered, but a labor charge can be added to a battery system quote. The battery must be operated within the environmental specifications and cycle life limits set by the battery vendor. Data recordkeeping is the responsibility of the user (like VRLA). If the evidence indicates that the battery has been misused: Samsung may cancel the 10-year warranty; LG Chem decrements the warranty coverage time length, depending on the degree of misuse (temperature and/or cycle count).
